The roofing system was engineered to support a modern, high-performance office environment and to align with the architectural goals of the Alta development. The design centered on maximizing energy efficiency, long-term durability, and clean integration with the building’s parapet features and mechanical infrastructure.

The white TPO membrane provides exceptional heat reflectivity—an important feature given Atlanta’s dense, heat-retaining urban environment—while also maintaining a sleek, uniform aesthetic across the rooftop.

• High-reflectivity TPO membrane reduces heat absorption and supports lower cooling costs
• Polyiso insulation package enhances thermal performance and energy efficiency
• Low-VOC adhesives and installation practices support safe and clean jobsite conditions
• Optimized drainage design reduces ponding risk and long-term maintenance requirements
• Durable, long-life materials support sustainability goals and reduce lifecycle wast

• Exterior: The final roofing system delivers a clean, bright, and seamless finish visible from surrounding high-rise buildings and nearby roadways. Parapet wall wrapping, penetration detailing, and edge metal integration were executed to meet high-rise commercial standards and to ensure long-term durability against Atlanta’s weather conditions.

• Interior: The upgraded insulation and high-performance membrane contribute to improved HVAC efficiency and stable interior temperatures—supporting the comfort requirements of modern office tenants and aligning with the building’s Class-A performance expectations.
